T0 (ZZZ whom it may comm.-

Be it known that LBOYD Hnnnscnuma citi- Zen of the United States, residing'at Wrightsville, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Padlocks; and I do doclare the following to be a full, clear, and ex-' act description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a partof this specification.

My invention relates to looks, more particularly to padlocks and it has for its objects to construct a padlock in which the key in ust be first turned in one direction and then in the opposite direction in order to withdraw the bolt, so as to unlock the shackle, also to provide a construction in which the locking-bolt will be connected with a lever, with which will be connected a key-catch, so that when the key is brought into engagement with said catch and caused to exert pressure thereon said lever will be moved, so as to retract the bolt, and thus release the shackle.

It has also for its object to provide a con: struction in which when the shackle is locked by the bolt a spring will tend to draw the shackle and bolt together, so as to hold the same firmly, which spring when the bolt is retracted will throw the shackle past the bolt and into its unlocked position.

It has also for its object to provide a construction in which the key-catch will be'under the influence of a spring, so that when the keyis pressed against said catch in the operation of bringing the key in to its operative position the catch willbe moved against the influence of said spring, and when the key has reached its operative position said spring will restore said catch to its normal position with a click, thus indicating thatthe key is in position so as to actuate the bolt by turning the key in an opposite direction; 1 and it has, further, for its object to provide a simple and efficient arrangement of parts adapted to operate substantially as hereinaftenset forth.

To the accomplishment of the foregoing and such other objects as may be made hereinafter to appear, the invention consists in the construction and in the arrangement of parts hereinafter particularly described, and then sought to be clearly defined by the claims, reference being had to the accompanying drawings, forming a parthereof, and in which-- Figure 1 is a front View of the padlock; Fig.

2, a similar view with the face-plate removed;

Fig. 3,a cross-section on line 3 3 of Fig. 2. Fig. at is a front view with face-plate removed and showing the position of the parts immediately upon releasing the shackle, and Fig. 5 a similar View showing the position of the parts to receive the shackle and lock the same.

In the drawings the numeral 1 designates the shell or case provided with the faceplate 2, which is secured thereto by the pins or rivets 3, the case or shell being provided with the hinged shackle 4.

The numeral 5 designates a lever, which preferably is mounted upon a fulcrum-pin 6, upon which it is free to turn, said lever having a locking-bolt 7, pivotally connected to,

one end,and a key-catch 8,piv0tall 'y connected .to the other end, the lever, locking-bolt and key-catch being held in their normal position y by the influence of a suitable spring 9 and restored by said spring to their normal position when moved therefrom. The locking-bolt 7 is guided in its movement by a lug 10 and is formed with a shoulder or abutment 11, which will bear against the lug 10 when the bolt is in its projected position, so that the lug will limit its forward movement. The bolt has secured to it a spring 12, which preferably is a flat spring and which will lie in the path of movement of the nose 13 of the shackle, so that when the shackle is depressed into its locked position said spring will be in contact with the shackles nose, and thus exert an outward pressure thereon. reason of being attached to the locking-bolt and bearing against the nose of the shackle will bind or draw the shackle and bolt toj 95. and against movement when locked, and

when the bolt is retracted said spring serves gether, so that the shackle will be held firmly to expel the shackle from the case or'shell by reason of its contractile strength when the bolt is retracted from engagement with'the nose of the shackle. formed with a recess 14 on its under face and in its normal position rests at its free end upon a lug or stud l5, and a suitable spring This spring by The key-catch 8 is 16 is so positioned in relation to the catch ,8

that if the key be turned to the left it"will contact with .said member, which member.

will prevent the key from being turnednto the left into operative position and compel it to be turned to the right, which movement to the. right will bring the bit or webof the key against the under side of the key-catch, which movement will lift the catch until the. bit of thekey enters the recess in the under face of the catch, and as soon as that occurs the spring 16 willthrow the catch down, which contacting with the lug will give a click, and thus indicate that the key is in operative position. The key is then turned to the left, which causes its bit or web to bear a'gainstthe wall of the recess 'inthe catch and to draw the catch forward, which movement turns the lever 5 and draws back or retracts the locking-bolt 7 from engagement with the nose of the shackle, whereupon the spring 12, exertingits pressure against'the shackles nose, throws theshackle out of the case or out of locking relation to the bolt. Pressure upon the key now being released, the spring 9 exerts its pressure, so as to restore the locking-bolt, the lever,and the keyc'atch to their normal position, and by turning. the key tothe right its bit or web'depresses the spring member 19 and passes the same, so that it may be Withdrawnfrom the lock case or shell. 7

It will be observed from the construction and arrangement of the parts as described that the key must first be turned in one direction to bring it into operative position and then in the opposite direction in order to actuate the bolt and throw it into its unlocked position. It will also be observed that the spring member prevents the key from being turned first into any other than its operative position, and yet after it has actuated the bolt the key is pressed past the spring member and brought into position to be withdrawn. Itswill also be observed that the spring attached to the locking-bolt will draw the bolt and shackle together when the shackle is locked, and thus hold the two in connection with each other, so that the shackle will not be loose, but will be held firmly, and it will be further observed that the spring bearing against the key-catch'w'ill cause the latter to make a click whenthe key is in operativeposition, so as to indicate that the key shall be reversed in its movement for the purpose of retracting the locking-bolt.

I have illustrated and described what I consider to be the preferred details of construction and arrangement of the several parts; but it is obvious thatchanges can be made therein and essential features of my invention still be retained.

Having described my invention and set forth its merits, what I claim is- 1. In a lock, the combination of the locking bolt, the centrally-fulcrumed lever pivotally connected atone end to the bolt, and the keycatoh, pivoted to said lever at its lower end below its fulcrum and'formed with a shoul- 8o der for thebit-of the key to engage with to move the catch and lower end of the lever forwardto retract the bolt, substantially as described. 7 a

2; In a lock,;the combination of the lockingbolt-having a forwardly-extending spring for the nose of the shackle to engage with, a cen-- trally fulcrumed lever pivotally connected at one end to the bolt, the key-catch pivoted to said lever at-its lower end below its fulcrum o andformed with a shoulder for the bit of the 1 key to engage. with to move the catch and lowerend of the lever forward to retract the tially as described.

' 4t. In a padlock, the combination of the shackle, the locking-bolt having a spring connected thereto to-engage the shackle, a lever with which said bolt is connected, a key-catch formed with a recess and pivotally connected with said lever, a spring acting on said keycatch, and a spring member located in relation to said key-catch to require the key to be moved in one directionto bring it into operative position and in the opposite direction to actuate the key-catch and permittingthe key'topass the spring member after it has actuated the key-catch, substantially as described. r .7 4

In testimony whereof I affix my signature in presence'of two witnesses.
